LOCK-HINGE.

SPECIFICATION forming part of Letters Patent No. 606,415, dated June 28, 1898. Application filed January 27, 1898- Serial No. 668,162. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM MARVIN Ho TALING, a citizen of the United States, residing at Port Ewen, in the county of Ulster and State of New York, haveinvented certain new and useful Improvements in Hinges; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in hinges for window-blinds; and the object is to provide a simple, inexpensive, durable, and efficient device for this purpose.

To this end the invention consists in the construction, combination, and arrangement of the device, as will be hereinafter more fully described, and particularly pointed out in the claim. T

The same reference characters indicate the same parts of the device in the several views.

Figure 1 is a front elevation of my improved hinge. Fig. 2 is a similar view showing the hinge open. Fig. 3 is a perspective view showing the two members separated.

1 denotes abracket formed with an integral circular horizontal plate 2, provided with a vertical tubular post 3, having a radial pin 4,. The upper face of the plate 2 is formed with a transverse shoulder 5, at one end of which is formed a recess 6.

7 denotes the movable bracket,.whichis secured to the blind or shutter, and it is formed with an integral circular horizontal plateB, I provided with an axial orifice 9 to receive the the lower plane portion 14 of the plate 2 to clear oh. the ice which may form and prevent the locking of the parts.

p The operation is as follows: When the blind is closed, the position of the parts is as shown in Fig. 1, and when the blind is opened the lug 13 sweeps the plate portion 14, being carried around until it comes into alinement with the recess 6, thereby allowing the upper plate to drop onto the lower plate, so that the two opposed shoulders 5 and 12 abut and form a lock to hold the shutter open. In closing the shutter it is only necessary to raise it the height of the lug 13 and then swing it to.

In such cases as bay-windows and where the construction is such as will not permit the blind to open full Way the shoulders 5 and 12 are arranged to permit the blind to open onebracket 1 formed with the horizontal plate 2 provided with the radial recess 6, the transverse shoulder 5, the vertical tubular post 3 and the radial pin 4, in combination with the movable bracket 7 formed with the horizontal plate 8 provided with the axial orifice 9 and radial communicatin g recess 10,the transverse shoulder 12 and thejdepending lug 13, substantially as shown and described.

In testimony whereof-1 have hereunto set my hand in presence of two subscribing witnesses.

WVILLIAM MARVIN HOTALING.
